4 Claims. (Cl. 24-407) This invention relates to new and usefulimprovements in closing and fastening means for garments, underwear,shoes, bags and the like; and it has for its principal object to providea device that will prove superior to those now in use on the market.

Another important feature of the invention,

resides in a slide fastener device which includes a novel locking pullmember for releasably securing the fastener device in open, closed, orany intermediate position.

The said device is of such a construction that it may be adaptable foragood many purposes and consequently will have a wide scope ofapplication.

Another advantage of the device is to the effect that the latter issimple to operate, sturdy and infallible in use, and may easily berepaired,

With the above and other objects in view, this invention consists of thenovel features of construction, combination and arrangement of parts,

hereinafter fully described, claimed and illustratedin the accompanyingdrawing forming part of this specification, and in which similarcharacters of reference indicate corresponding parts in all views, andin which:

Figure 1 is a plan view of my invention showing the fastening device inpartially open position.

Figure 2 is a plan view of the sliding or manipulating member of mydevice per se, upper surface thereof.

Figure 31s a transverse sectional view on the line 3-3 of Figure 1, withthe clamping member 'in released position.

Figure 4 is a perspective view of one of the slidefastener elements perse. Figure 5 is a longitudinal sectional view taken on the line 5-5 of:Figure 1.

Figure 6 is a perspective view of the locking member per se. 7 I c JReferring more particularly to the drawing, 10 indicates a portion .ofan article to which my, de-

' vice is applicable; the present purpose of the said device being, as.will appear evident, to open or close the separable flexible flaps IIand I2 constituting opposite sides of an opening provided in the article10'. The flaps II and I2 are provided with beads lI-li on theirrespective inner edges. inwardly 0! the plane of the flaps arshowing the-ranged a flexible strip ll of a length approximating the length of thebeaded edges I3. The strip i4 is preferably in the form of a. length offabric tape,but may be of any other suitable flexible material ifdesired. The strip M has at.- tached thereto, a plurality of slidefastener elements l5, one of which is shown per se in Figure 4. Each ofthe slide fastener elements includes a relatively flat base 9 havingthread openings i6 therein for securing them, for instance by sewing tothe strip l4, and in addition, the outer face of the base is providedwith grooves l1 into which the openings lli open to receive the sewthreads, or the cement or glue 'in case it should be desired to securethe fastener elements "IE to the strip It in the said latter manner. Thefastener elements ii are secured to the strip it at intervals and eachfurther includes a head l8 of less width than the base 9 and which headextends outwardly from the base 9. The outer opposite side edges'of thehead are rounded as at l9--l9, while opposite sides of the head areprovided bead receiving grooves or channels 2020 which are circular incross section and open outwardly to respectively and slidably re- 'ceivethe beads i3l3. w

The flexible element I4 is fixedly secured by stitching 29 to the flapsII and- I! at one end of the opening which the device is adapted to openor close, while the opposite end of the-flexible element is free and hasattached thereto a' manipulable releasable lock fastener memberll. Thefastener member 2| has a flat base 22 for securing it to, the flexibleelement It, for instance by sewing; the apertures 23 in the base beingshown for that purpose; The fastener member width less than the width ofthe base and which- 2| also includes a reduced integral head 26 of a isflush with the'inner end of the base but which combined manipulatingpull and lock'tongue 25 is pivotally connected. The furcations at thebifurcated end of the tongue are provided with cam 'portions 21 disposedin alinement with the bead receiving channels 2|! in opposite sides ofthe head 26. The tongue 25 serves as a manipulating pull element forslidably actua ting the device to open and closed'positions, and alsoobnstitutes a means by which the fastener member 2| may be releasablyheld against sliding movemerit in any of its positions along the lengthof the beads l3--l3.'

The releasing and fastening operation above referred to is performed bythe cam portions 21 on the tongue 25, for when pushed inwardly to theposition shown in Figure'S' the same tightly grip the beads |3I3 of theflaps II and I2 against the base 22. By clamping the slide fastenermember 2| to the beads l3l3, the fastening device is locked againstoperation, but upon pulling outwardly upon the tongue 25 to the positionshown in Figure 3, the member 2| is released and free to slide with thefastener elements l5.

It will'be understood that when the fastening device is in fully closedposition the slide fastener elements will be disposed at spaceddistances along the length of the beads. During the initial openingoperation, the flat inner end of the manipulable fastener member 2|flatly contacts the adjacent flat end of the next fastener member I5 toimpart a straight push to avoid binding or jamming which would result ifthe engaging members did not contact simultaneously on both the innerand outer sides of the beads Hi. The other adjacent fastener memberssimilarly engageeach other as the manipulable pull fastener member movesto the limit of its opening movement, at which time all the adjacentends of the fastener members will be in flat contacting engagement.

When the slide fastener device is in fully closed position, the flexiblestrip l4 underlies the joint between the adjacent beaded edges l3-l3 andserves to close the full length of the same.

It is obvious that changes may be made in the form, construction andarrangement of parts, as shown, within the scope of the appended claims,without departing from the spirit of the invention, and I do nottherefore wish to limit myself to the construction and arrangement shownand described therein.

Having thus described the invention, what I claim as new and desire tosecure by Letters Patent of the United States, is:-

1. A device of the class described, comprising in combination, a pair offlexible members to be fastened together, beads upon adjacent edges ofthe flexible members, a strip of flexible material arranged inwardly ofthe flexible members and having one of itsends fixedly connectedthereto, fastener members secured to the said strip at intervalstherealong, each of the said fastener members comprising a base, and ahead extending outwardly from said base having grooves in opposite sidesthereof receiving the resepective beads, the base having stitchreceiving openings and grooves receiving sew-on threads for-securing thefasteners to said strip of flexible material, a manipulating slidefastener member mounted at the free end of said strip of pliablematerial, said manipulating fastener member including a base and a head,a manipulating tongue pivotally 2. A device of the class described,comprising,-
